Chapter 2 Hardware Configuration

This section provides information on jumper settings and connectors on the YMBAO100 in order to set up a workable system. The topics covered are:

• M.2 card Installation

• Jumper and connector locations

• Jumper settings and information of connectors

10

2.1 Mini-PCIe & M.2 Card Installation

To install the mini-PCIe and M.2 cards, perform the following steps.

1. Locate the mini-PCIe slot, align the key of the mini-PCIe card to theinterface, and insert the card slantwise.

(Insert the M.2 card in the same way.)

2. Push the mini-PCIe card down and fix it with 2 flat head screws.

(Fix the M.2 card with one screw.)

2.2 Setting the Jumpers

Set up and configure your YMBAO100 by using jumpers for various settings and features according to your needs and applications. Contact your supplier if you have doubts about the best configuration for your use.

2.2.1 How to Set Jumpers

Jumpers are short-length conductors consisting of several metal pins with a non-conductive base mounted on the circuit board. Jumper caps are used to have the functions and features enabled or disabled. If a jumper has 3 pins, you can connect either PIN1 to PIN2 or PIN2 to PIN3 by shorting.

Pin# 1 2 3

A 3-pin jumper A jumper cap

Refer to the illustration below to set jumpers.

Pin closed Oblique view Schematic illustration in the manual

Open 1 2 3

1-2 1 2 3

2-3 1 2 3

When two pins of a jumper are encased in a jumper cap, this jumper is

closed, i.e. turned On.

When a jumper cap is removed from two jumper pins, this jumper is open,

i.e. turned Off.

Chapter 3 Software Setup

This chapter introduces installation of the following drivers:

• Make a recovery SD card (for advanced users only)

• Display parameter setting in kernel

24

3.1 Make a Recovery SD Card

Note: This is for advanced users who has i-Tech standard image file only.

Basically, YMBAO100 is preloaded with O.S (Android / Linux) intoeMMC by default. Connect the TFT-LCD with IBR117 (or HDMI), and 12V power directly.

This chapter guides you to make a recovery boot-up SD card. i-Tech optionally provides 7” /15” / 21.5” LVDS panel and HDMI display for you to prepare the software application pre-development easily under Linux platform.

3.1.1 Preparing the Recovery SD Card to Install Linux /

Android Image into eMMC

Note: All data in the eMMC will be erased.

1. System requirements:Operating System: Windows 7 or laterTool: mfgtools-2.3SD card: 4GB or greater in size

2. Insert your SD card to this board (i.e. the P3 connector), connect theboard to PC through the mini-USB port (i.e. the P6 connector), andchange the boot mode to burning state.

Driver Installation

25

3

3. Copy the image to the directory mfgtools-2.3\Profiles\Linux\OS Firmware\files\YMBAO100\.

4. Select the script of mfgtools sdcard recovery.

5. Start burning image to SD card. When the image buring finishes, therecovery SD card is ready.

3.1.2 Upgrade Firmware through the Recovery SD Card

1. Copy the image files (what you want to upgrade) to U

disk /YMBAO100/recovery/.

2. Insert the recovery SD card and U disk to the board for upgrade.

3. Power up the board and the recovery program starts.

4. When the recovery finishes, power down the board, pull out therecovery SD card and U disk.

Driver Installation

27

Chapter 4 BSP Source Guide

This chapter is dedicated for advanced software engineers only to build BSP source. The topics covered in this chapter are as follows:

• Preparation

• Installing Toolchain

• Building U-Boot

• Building Kernel

• Building RAMdisk Image (Optional)

• Installing Linux to SD Card

• Booting with your SD Card

BSP Source Guide

29

4

4.1 Preparation

The suggested Host platform is Ubuntu 12.04 and 14.04 in 32-bit and 64-bit versions.

1. Install necessary packages before building:

sudo apt-get install gawk wget Git-core diffstat unzip texinfo

sudo apt-get install gcc-multilib build-essential chrpath socat

sudo add-apt-repository ppa:git-core/ppa

sudo apt-get update

sudo apt-get install git

sudo apt-get install texinfo

2. Decompress the YMBAO100 source file YMBAO100.tar.xz into "/home/"

folder.

4.2 Installing Toolchain

Decompress Toolchain poky.tar into directory "/opt".

4.3 Building U-Boot

cd /home/YMBAO100

cd YMBAO100-x11/tmp/work/imx6dlsabresd-poky-linux-gnueabi/u-boot-

imx/2016.03-r0/git source /opt/poky/1.8/environment-setup-cortexa9hf-vfp-neon-

poky-linux-gnueabi make mx6dlsabresd_defconfig

make

4.4 Building Kernel

cd /home/YMBAO100

cd ibr117-x11/tmp/work/imx6dlsabresd-poky-linux-gnueabi/linux-imx/4.1.15-r0/git

source /opt/poky/1.8/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi

make imx_v7_defconfig

make zImage LOADADDR=0x10008000

make imx6dl-sabresd.dtb

30

4.5 Building RAMdisk Image (Optional)

1. Enter YMBAO100.

cd /home/YMBAO100

2. Running the script below.

./build.sh YMBAO100

3. See the image in the "release" directory.

ls release/YMBAO100-20170519-030011/

rootfs.tar.bz2 u-boot-imx6dlsabresd.imx zImage zImage-imx6dl-sabresd.dtb

4.6 Install Linux to SD Card

1. Refer to the section 3.1 Make a Recovery SD Card in chapter 3.

2. Run the make card script below.

./make_sd.sh /dev/sdd 20150814-111827

3. The appearance of the sentence "SD card for booting create done"indicates the installation is successfully done.

4. Pull out the SD card.

4.7 Booting with Your SD Card

Insert SD card to your board and insert special COM port dongle to boot from SD. Connect a debug cable to debug port with serial port 115200/N/8/1 setting on your PC’s serial port program, such as hyperterminal/teraterm. Connect LVDS 15” display panel. Power on and you will see U-Boot prompt.

If you want to change to another monitor (or display panel) type, refer to the section 3.2 Display Parameter Setting in Kernel to set video output command.

C. eMMC Test

Note: This operation may damage the data stored in eMMC flash. Before starting the test, make sure there is no critical data in the eMMC flash being used.

• Read, write, and check

MOUNT_POINT_STR="/var"

#create data file

dd if=/dev/urandom of=/tmp/data1 bs=1024k count=10

#write data to emmc

dd if=/tmp/data1 of=$MOUNT_POINT_STR/data2 bs=1024k count=10

D. USB (flash disk) Test

Insert the USB flash disk then assure it is in YMBAO100 device list.

Note: This operation may damage the data stored in the USB flash disk. Before starting the test, make sure there is no critical data in the eMMC flash being used.

#create data file

dd if=/dev/urandom of=/var/data1 bs=1024k count=100

#write data to usb flash disk

E. SD Card Test

When YMBAO100 is booted from eMMC, SD card is “/dev/mmcblk1” and

able to see by “ls /dev/mmcblk1*” command:

/dev/mmcblk1 /dev/mmcblk1p2 /dev/mmcblk1p4 /dev/mmcblk1p5 /dev/mmcblk1p6

When YMBAO100 is booted from SD card, replace test pattern “/dev/mmcblk1” to “/dev/mmcblk0”.

Note: This operation may damage the data stored the SD card. Before starting the test, make sure there is no critical data in the eMMC flash being used.


SD_DIR="/run/media/mmcblk1"

#create data file


#write data to SD card

dd if=/var/data1 of=$ SD_DIR/data2 bs=1024k count=100


cmp $SD_DIR/data2 /var/data1

• SD card speed test
